This patch adds a new transmit path for hardware that supports 802.11
encapsulation offloading. In those cases 802.3a frames get passed
directly to the driver allowing to hardware to handle the encapsulation.
Certain features wont work and the patch masks these out.
* monitor interfaces are not supported if any of the vif is in encap mode.
* amsdu/non-linear frames wont work in encap offloading mode.
* TKIP countermeasures cannot be triggered and hence those keys are not
accepted.
The patch defines a secondary netdev_ops struct that the device is assigned
to the device if 802.11 encap support is available and enabled. The driver
needs to enable the support on a per vif basis if it finds that all
pre-reqs are meet.
